Abstract:
In examples, a sensor package comprises a die pad and a semiconductor die on the die pad. The semiconductor die has an active surface. The sensor package includes a light sensor on the active surface of the semiconductor die. The sensor package includes a mold compound covering the die pad, the semiconductor die, and a portion of the active surface. The sensor package includes a light filter covering the light sensor and abutting the mold compound. The light filter includes a combination of silicone, metal particles, and an organic dye. The combination is configured to reject light having a wavelength in a target wavelength range. The light filter has a thickness of at least 0.5 millimeters.
